ClearEffect of hydrocyclone design in microplastics-water separation by using computational fluid dynamics simulations
Researchers used computer fluid dynamics simulations to test and optimize the design of hydrocyclones — spinning funnel-shaped devices that use centrifugal force to separate particles from water — for removing microplastics, finding an optimized geometry that achieved 76% microplastic recovery. The results show that carefully tuning the proportions of a hydrocyclone's components can significantly improve its ability to filter microplastics from water at scale.
